Risk analysis in the operation of waste electrical and electronic equipment recycling plants. The identification and evaluation of environmental and occupational health risks are essential tools in the prevention of accidents and environmental protection.

Electronic Waste: A Growing Concern in Today's Environment

Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution. Electronic scrap components, such as CPUs , contain potentially harmful materials such as lead , cadmium , beryllium , or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and their communities. E-waste or electronic waste is created when an electronic product is discarded after the end of its useful life.

Cleaning Up Electronic Waste (E-Waste)

Khurrum S. Over the recent past, the global market of electrical and electronic equipment EEE has grown exponentially, while the lifespan of these products has become increasingly shorter. More of these products are ending up in rubbish dumps and recycling centers, posing a new challenge to policy makers. The purpose of this paper is to provide a review of the e-Waste problem and to put forward an estimation technique to calculate the growth of e-Waste. Over the past two decades, the global market of electrical and electronic equipment EEE continues to grow exponentially, while the lifespan of those products becomes shorter and shorter. Therefore, business as well as waste management officials are facing a new challenge, and e-Waste or waste electrical and electronic equipment WEEE is receiving considerable amount of attention from policy makers.

E-waste comprises discarded electronic appliances, of which computers and mobile telephones are disproportionately abundant because of their short lifespan. Most E-waste is disposed in landfills. Effective reprocessing technology, which recovers the valuable materials with minimal environmental impact, is expensive.

Electronic Waste: A Growing Concern in Today's Environment

Electronic and electric waste e-waste , defined as end-of-life electronic products, including computers, television sets, mobile phones, transformers, capacitors, wires and cables, are a major global environmental concern. The crude recycling of e-waste releases persistent toxic substances, such as heavy metals, polybrominated diphenyl ethers PBDEs , polychlorinated dibenzodioxins PCDDs , polychlorinated dibenzofurans PCDFs , polycyclic aromatic hydrocarbons PAHs and polychlorinated biphenyls PCBs , and the environmental pollution and health risks caused by the improper disposal of e-waste has become an urgent issue. This book offers an overview of e-waste history, sources, and entry routes in soil, air, water and sediment. It also addresses e-waste transport and fate, bioavailability and biomonitoring, e-waste risk assessment, impacts on the environment and public health. In addition, it discusses the impact of e-waste on soil microbial community diversity, structure and function and reviews the treatment and management strategies, such as bioremediation and phytoremediation, as well as policies and future challenges.

Health Promot , 4 2 : Back to browse issues page. The Status of Electronic Waste in Iran. Background: The present study aimed to estimate the flow of electronic waste e-waste in Iran in order to establish a baseline for these toxic, potentially valuable wastes. Methods: Questionnaires were prepared to determine the amount of waste produced by households, institutions, repair centers, and importers and sellers of electronic products. In total, questionnaires were completed via face-to-face interviews.

Electronic Waste Pollution

Some of the work undertaken by UNU-Step included tracking global flows of e-waste, the Person-in-the-Port project in Nigeria, optimization of an e-waste dismantling facility in Ethiopia and the development of a tool to help gather information on volumes of e-waste generated within countries and exported to others. Managing the e-waste created by an increasing amount of computer and telecommunication equipment is important to the Ethiopian government, and many international partners have worked in Ethiopia to help address this concern. The project also strengthened the capacity of a demanufacturing facility to process e-waste in Addis Ababa.

Developmental Neurotoxicants in E-Waste: An Emerging Health Concern

Electronic waste e-waste has been an emerging environmental health issue in both developed and developing countries, but its current management practice may result in unintended developmental neurotoxicity in vulnerable populations. To provide updated information about the scope of the issue, presence of known and suspected neurotoxicants, toxicologic mechanisms, and current data gaps, we conducted this literature review. We reviewed original articles and review papers in PubMed and Web of Science regarding e-waste toxicants and their potential developmental neurotoxicity. We also searched published reports of intergovernmental and governmental agencies and nongovernmental organizations on e-waste production and management practice. We focused on the potential exposure to e-waste toxicants in vulnerable populations—that is, pregnant women and developing children—and neurodevelopmental outcomes. In addition, we summarize experimental evidence of developmental neurotoxicity and mechanisms.

Расстроенный, Беккер повесил трубку. Провал. Мысль о том, что придется отстоять в очереди несколько часов, была невыносима. Время идет, старик канадец может куда-нибудь исчезнуть.

Она в конце концов перестала протестовать, но это продолжало ее беспокоить. Я зарабатываю гораздо больше, чем в состоянии потратить, - думала она, - поэтому будет вполне естественным, если я буду платить. Но если не считать его изрядно устаревших представлений о рыцарстве, Дэвид, по мнению Сьюзан, вполне соответствовал образцу идеального мужчины. Внимательный и заботливый, умный, с прекрасным чувством юмора и, самое главное, искренне интересующийся тем, что она делает. Чем бы они ни занимались - посещали Смитсоновский институт, совершали велосипедную прогулку или готовили спагетти у нее на кухне, - Дэвид всегда вникал во все детали.
